Support cloning based on Language

[giannisgrigorakos]

Is your feature request related to a problem? Please describe.
Sometime you want to clone only repos limited to your craft. e.g. if I'm a backend engineer I would like to clone only repos related to Go and PHP.

Describe the solution you'd like
Maybe we could parse a flag like GHORG_LANGUAGE which will actually be an enum containing all the supported languages of github/gitlab/.... Then based on this flag it will download only the repos that have as a base language this one.

Describe alternatives you've considered

Sounds fun, it looks like the github api returns the language of the repo, not sure of the other providers tho. I would propose GHORG_MATCH_REPO_LANGUAGE to be similar to existing matching flags.
